title: [Pulmonary artery pressure and blood gas composition in the acute period of myocardial infarct].
abstract: The mean pressure in the pulmonary artery and the gaseous composition of arterial, capillary, venous and mixed venous blood were studied in 40 patients with acute myocardial infarction. It was found that increased pressure in the pulmonary artery is congruous with low oxygen and carbon dioxide tension in arterial and capillary blood. Oxygen tension in venous blood was low while carbon dioxide tension was increased. Since increased pressure in the pulmonary artery was predominantly found in patients with cardiac insufficiency, the authors suggest using the data obtained in the comprehensive appraisal of the condition of hemodynamics and the efficacy of treatment.
